Splitting of the Superfluid Transition in Liquid He-3 Induced by a Nematic Aerogel

摘要

The effect of inhomogeneous perturbations created by a nematic aerogel in liquid He-3 on the form of the order parameter arising at the transition to the superfluid state is studied. It is shown that the stability boundary of the distorted polar Anderson-Brinkman-Morel phase can arise just on the superfluid transition line at certain characteristics of the nematic aerogel. A symmetry-based argumentation for the choice of aerogels most suitable for stabilizing the polar phase is given.
